The pump in Ebershpeher won't start, it pumps but gives out an error. What can it be?

If the pump is pumping, it indicates that there are no faulty elements in the electric circuit of the heater, i.e.е. It has passed the test before starting. In this case the defect may be in the mechanical part, which is not diagnosed electronically. It could be soot in the combustion chamber, evaporator-grid coking, the pump wear (pumps fuel, but not enough) or it could be simply clogged with something or air in the fuel pipe. There are a lot of variants. You need to look at the error code in the heater memory and base your calculations on that.
